L-band transmission over 1000km using standard and dispersion-compensating fibres in pre-compensation scheme optimised at 1550nm

Transmission over 1000km of a 10Gbit/s signal at 1597nm is demonstrated in a recirculating loop using standard fibre and wideband dispersion-compensating fibre in the pre-compensation configuration. It is shown that dispersion maps optimised for 1550nm can be successfully used in the L-band, removing the need for separate band dispersion compensation.
